Complete the SQL statement.
For information on writing SQL statements that modify databases, consult a Transact-SQL manual.

Use the Variables area to define any SQL variables. Provide the name and run-time value. Specifying the type and
size of each variable prevent injection attacks.
The following example shows an Insert statement that contains three SQL variables. The values of these variables are
provided by URL parameters passed to the page, as defined in the Run-Time Value column of the Variables area.
To get the Size value, use the Databases panel in Dreamweaver. Find your database in the Databases panel and
expand it. Next, find the table you’re working with and expand it. The table lists the sizes for your fields. For example,
it might say ADDRESS (WChar 50). In this example, 50 is the size. You can also find the size in your database appli-
cation.
Note: Numeric, Boolean and date/time data types always use -1 as the size.
To determine the Type value, see the following table:
