Executes an SQL statement directly.
If you plan to interpolate PHP variables into the SQL statement, understand that this is one of the more common security exposures. Consider calling db2_prepare to prepare an SQL statement with parameter markers for input values. Then you can call db2_execute to pass in the input values and avoid SQL injection attacks.
If you plan to repeatedly issue the same SQL statement with different parameters, consider calling db2_prepare and db2_execute to enable the database server to reuse its access plan and increase the efficiency of your database access.
A valid database connection resource variable as returned from db2_connect or db2_pconnect.
An SQL statement. The statement cannot contain any parameter markers.
An associative array containing statement options. You can use this parameter to request a scrollable cursor on database servers that support this functionality.
For a description of valid statement options, see db2_set_option.
Returns a statement resource if the SQL statement was issued successfully, or false if the database failed to execute the SQL statement.
