This syntax cannot span lines and is used for SQL statement. The following list points out what you can do with this syntax and what you should pay attention to.

  • This syntax can be used to generate any variable value, and also the value of any existing parameter.

  • No space char is allowed after <%=.

  • Inside this syntax, the <%...%> or </.../> syntax should not be used.

The statement written in the below example is a valid one.

#sql sentence
DROP TABLE temp_<%=__TABLE_NAME__ %>;

The code is used to remove the table defined through an associated component.

For more information about what components are associated with the SQL templates, see Designing a Job.

For more information on the <%...%> syntax, see the previous section.

For more information on the </.../> syntax, see the following section.

Note

Parameters that the SQL templates can access with this syntax are simple. They are often used for connection purpose and can be easily defined in components, such as TABLE_NAME, DB_VERSION, SCHEMA_TYPE, etc.
