Aqueduct SQL Methods Changes
AqueductSQLMethods 1.2.1
Bugs Fixed
- The new Aqueduct.Results module was ommitted.
AqueductSQLMethods 1.2
Bugs Fixed
- Source changes were lost when resizing the editing screen.
- When testing, on DAs that use new DA protocol,
non-select SQL is reported as such.
Features Added
- Support for new Aqueduct DA protocol, providing much faster
retrievals.
- Edit screen size preferences are now distinct from Document
size preferences.
AqueductSQLMethods 1.1.5
Features Added
- Added permission settings to work with recent Principia versions.
Aqueduct SQL Methods 1.1.4
Bugs Fixed
- Generated reports failed in cases where column names contained
odd characters, as would be the case with::
select salary*1.2 from payrole
Aqueduct SQL Methods 1.1.3
Bugs Fixed
- Changed permission settings to be in line with principia 1.2
Aqueduct SQL Methods 1.1.2
Bugs Fixed
- If strings contained backslashes but not backslash-t or
backslash-n, then the backslashes were getting doubled.
Aqueduct SQL Methods 1.1.1
Bugs Fixed
- The SQL string quoting done by the sqlvar and sqltest tags
failed on non-ANSI-SQL databases like mySQL. Extra hooks
were added to allow database adapters to provide custom quoting
logic.
Aqueduct SQL Methods 1.1.0
Features
- New DTML tags are available in SQLMethods that greatly
improve the ease, safety, and flexibility of database methods.
- SQL Templates are now rendered in the context of the containing
folder, rather than the method itself.
- Input arguments are shown in input forms in the order that
they were defined, rather than in alphabetical order.
Aqueduct SQL Methods 1.0.5
Features Fixed
- Database methods are slightly better about binding themselves
to the correct object when acquired.
Aqueduct SQL Methods 1.0.4
Features Fixed
- RDBMS transaction boundaries now coincide with Principia
tranasaction boundaries. For example, if a Document
runs 3 database methods and the third method raises an error,
then the other methods are aborted.
Aqueduct SQL Methods 1.0.3
Bugs Fixed
- Add permissions were not editable.
- Methods on database records could not use acquired attributes.
AqueductSQLMethods 1.0.1
Bug Fixes
- Error reporting was broken in test mode.
Features
- Include generated SQL source in test output.
ZSQLMethods
The ZSQLMethods product provides support for SQL Method objects
which can be used in conjunction with any database adapter to
use relational database data from within the Zope environment.

Z SQL Method Object: Query relational databases with SQL
Description
Z SQL Methods allows you to access data in SQL databases.
Z SQL Methods define and call SQL statements on databases which
are defined by database adapter objects. To create a new Z SQL
Method you will need to setup a database adapter first. Every Z
SQL Method is directly linked to a database connection through a
database adapter.
**Note:** You must associate a Z SQL method with a database
adapter. If Zope cannot find a database adapter from your
location, you will not be able to create a Z SQL Method.
Z SQL Method - Add: Create new Z SQL Method
Description
This view allows you to create a new Z SQL Method.
Controls
'ID' -- Specifies the id of the sql method.
'Title' -- Specifies the title of the sql method.
'Connection id' -- Select list that specifies the database
connection on which the sql method operates.
**Note:** If you change the ID of your DB Connection object, all
the Z SQL Methods using this connection object will *NOT* be
updated. You have to update all Methods one by one.
'Arguments' -- Allows you to specify a list of arguments that the sql
method takes. The arguments should be separated by spaces or
a newline in the field. Furthermore, you can specify the
type of the argument as well as a default
value.
**Example:** 'title:string="No title!"', where 'title' is the
attribute, 'string' is the type of the attribute, and '"No
title!"' is the default value.
'Query template' --
Text area that specifies the SQL query that will execute when
this method is called. The query template can contain DTML
markup to tailor the SQL statement to the arguments. There are
three additional DTML tags called 'SQLVAR', 'SQLTEST', and
'SQLGROUP'. Please refer to their references get more details on
how to use them in your SQL statement.
**Note:** the SQL statement need not be a 'SELECT' query, it may
be any valid SQL statement including an INSERT or UPDATE.
**Important:** You can have several SQL statements in one ZSQL
Method.
Z SQL Method - Advanced: Manage advanced settings
Description
Manage the advanced settings such as caching and plugable
brains of a SQL method.
Controls
'ID' -- Indicates the id of the sql method.
'Title' -- Allows you to specify the title of the sql method.
'Connection Hook' -- Specifies the id of a method to be called when the database connection is made. This method will return a string containing the id of the database connection to use. If left blank there is no effect, the connection id specified will be used.
'Maximum number of rows retrieved' -- Specify an upper limit
for the number of rows a sql method can retrieve. Setting this
option correctly (based on your specific environment) can
increase the execution time of the method.
'Maximum number of results in the cache' -- Set the size of
the sql method cache.
'Maximum time (seconds) to cache results' -- The time in
seconds that results are cached. Setting to zero disables
caching.
Rows returned from this method can be turned into 'Result
objects' that are instances of a class you can specify below.
'Class name' -- Allows you to specify the name of the Python class.
'Class file' -- Allows you to specify the name of the Python
module that the class is defined in. The class file should
reside in the Zope 'Extensions' directory.
Z SQL Method - Edit: Change attributes of a SQL method
Description
This view allows you to edit the attributes of a SQL method.
Controls
'ID' -- Specifies the id of the sql method.
'Title' -- Specifies the title of the sql method.
'Connection id' -- Select list that specifies the database
connection on which the sql method operates.
**Note:** If you change the ID of your DB Connection object, all
the Z SQL Methods using this connection object will *NOT* be
updated. You have to update all Methods one by one.
'Arguments' -- Allows you to specify a list of arguments that the sql
method takes. The arguments should be separated by spaces or
a newline in the field. Furthermore, you can specify the
type of the argument as well as a default
value.
**Example:** 'title:string="No title!"', where 'title' is the
attribute, 'string' is the type of the attribute, and '"No
title!"' is the default value.
'Query template' --
Text area that specifies the SQL query that will execute when
this method is called. The query template can contain DTML
markup to tailor the SQL statement to the arguments. There are
three additional DTML tags called 'SQLVAR', 'SQLTEST', and
'SQLGROUP'. Please refer to their references get more details on
how to use them in your SQL statement.
**Note:** the SQL statement need not be a 'SELECT' query, it may
be any valid SQL statement including an INSERT or UPDATE.
**Important:** You can have several SQL statements in one ZSQL
Method.
Z SQL Method - Test: Test the validity of your SQL statement
Description
Test a SQL method.
Controls
'*[arument names]*' -- There will be one text field for each
argument specified for the SQL method. The text field will
contain the default value. **Important:** You must enter a
value matching the specified argument type, otherwise a "Type
Error" is returned.
'Submit Query' -- Causes the query to be executed and the
results are returned as an HTML table. If the query was had a
syntax error or the accessed table did not exist, a
database-specific error message is returned in form of an
exception.
If you have a SQL statement that does not return any data,
Zope will tell you that this SQL statement was not a
query and will not display any results.

"""Inserting optional tests with 'sqlgroup'
It is sometimes useful to make inputs to an SQL statement
optinal. Doing so can be difficult, because not only must the
test be inserted conditionally, but SQL boolean operators may or
may not need to be inserted depending on whether other, possibly
optional, comparisons have been done. The 'sqlgroup' tag
automates the conditional insertion of boolean operators.
The 'sqlgroup' tag is a block tag. It can
have any number of 'and' and 'or' continuation tags.
The 'sqlgroup' tag has an optional attribure, 'required' to
specify groups that must include at least one test. This is
useful when you want to make sure that a query is qualified, but
want to be very flexible about how it is qualified.
Suppose we want to find people with a given first or nick name,
city or minimum and maximum age. Suppose we want all inputs to be
optional, but want to require *some* input. We can
use DTML source like the following::
<dtml-sqlgroup required>
<dtml-sqlgroup>
<dtml-sqltest name column=nick_name type=nb multiple optional>
<dtml-or>
<dtml-sqltest name column=first_name type=nb multiple optional>
</dtml-sqlgroup>
<dtml-and>
<dtml-sqltest home_town type=nb optional>
<dtml-and>
<dtml-if minimum_age>
age >= <dtml-sqlvar minimum_age type=int>
</dtml-if>
<dtml-and>
<dtml-if maximum_age>
age <= <dtml-sqlvar maximum_age type=int>
</dtml-if>
</dtml-sqlgroup>
This example illustrates how groups can be nested to control
boolean evaluation order. It also illustrates that the grouping
facility can also be used with other DTML tags like 'if' tags.
The 'sqlgroup' tag checks to see if text to be inserted contains
other than whitespace characters. If it does, then it is inserted
with the appropriate boolean operator, as indicated by use of an
'and' or 'or' tag, otherwise, no text is inserted.

'''Inserting values with the 'sqlvar' tag
The 'sqlvar' tag is used to type-safely insert values into SQL
text. The 'sqlvar' tag is similar to the 'var' tag, except that
it replaces text formatting parameters with SQL type information.
The sqlvar tag has the following attributes:
name -- The name of the variable to insert. As with other
DTML tags, the 'name=' prefix may be, and usually is,
ommitted.
type -- The data type of the value to be inserted. This
attribute is required and may be one of 'string',
'int', 'float', or 'nb'. The 'nb' data type indicates a
string that must have a length that is greater than 0.
optional -- A flag indicating that a value is optional. If a
value is optional and is not provided (or is blank
when a non-blank value is expected), then the string
'null' is inserted.
For example, given the tag::
<dtml-sqlvar x type=nb optional>
if the value of 'x' is::
Let\'s do it
then the text inserted is:
'Let''s do it'
however, if x is ommitted or an empty string, then the value
inserted is 'null'.
