ABAPWHERE_DYNAMIC - WHERE DYNAMIC

Effect

Dynamic WHERE condition. For cond_syntax any character-like data object or standard table with character-like line type can be specified that, when the statement is executed and with the following exceptions, contains the syntax of a logical expression in accordance with the rules of the static WHERE condition or is initial. The following are not supported in a dynamic WHERE condition:

• String expressions and bit expressions

• String functions and bit functions

• Time stamp functions with the exception of utclong_current

• Constructor expressions

• Table expressions

The syntax in cond_syntax is not case-sensitive as in the static syntax. When an internal table is specified, the syntax can be distributed across multiple lines. If cond_syntax is initial when the statement is executed, the logical expression is true. Invalid logical expressions raises an exception from the class CX_SY_ITAB_DYN_LOOP. See Security Risks Caused by Input from Outside.

Note

The dynamic WHERE condition is not evaluated for an empty table for optimization reasons. Therefore, if an internal table is empty, and a logical expression has errors, no exception is raised.
