- sqlvar: Inserts SQL variables
-
- The 'sqlvar' tag safely inserts variables into SQL code. This tag
- is used in SQL Methods.
-
- Syntax
-
- 'sqlvar' tag syntax::
-
- <dtml-sqlvar Variable|expr="VariableExpression">
-
- The 'sqlvar' tag is a singleton. Like the 'var' tag, the 'sqlvar'
- tag looks up a variable and inserts it. Unlike the var tag, the
- formatting options are tailored for SQL code.
-
- Attributes
-
- type=string -- The type of the variable. Valid types include:
- 'string', 'int', 'float' and 'nb'. 'nb' means non-blank
- string. The type attribute is required and is used to properly
- escape inserted variable.
-
- optional=boolean -- If true and the variable is null or
- non-existent, then nothing is inserted.
-
- Examples
-
- Basic usage::
-
- select * from employees
- where name=<dtml-sqlvar name type="string">
-
- This SQL quotes the 'name' string variable.
