SELECT - WHERE

Syntax


... [FOR ALL ENTRIES IN itab] WHERE sql_cond ...

Effect

The addition WHERE restricts the number of lines included in the result set by the statement SELECT, by using a logical expression sql_cond. The logical expression compares the content of columns in the database with the content of host variables, literals, or with the content of other columns. The optional addition FOR ALL ENTRIES can be used to compare the content of a column in the database with a component with all lines of a structured internal table itab.

The logical expression sql_cond is either true, false, or unknown. The expression is unknown if one of the columns involved in the database contains a null value and is evaluated with another comparison as IS NULL. A row is only included in the results set if the logical expression is true.

Except for columns of type STRING or RAWSTRING plus LCHR or LRAW or the obsolete VARC, all columns of the database tables or views specified after FROM can be evaluated after the WHERE condition. The columns do not necessarily have to be a part of the results set.


Notes

  • The client ID cannot be queried in the WHERE condition, if automatic client handling is not deactivated using the addition CLIENT SPECIFIED after FROM. This is usually tested by the syntax check. If the client ID is queried in the WHERE condition and CLIENT SPECIFIED is not specified (which is sometimes the case when using alternative table names, in joins, and when specified dynamically), automatic client handling is not switched off. In this case, there are two conditions for the client column: the implicit condition of the automatic client handler for the current client and the explicitly specified condition. If the current client is not specified in the explicitly specified condition, the result set is empty.
  • The WHERE condition of the SELECT statement described here includes the WHERE conditions of the Open SQL statements DELETE, OPEN CURSOR, and UPDATE.
  • The logical expressions of the WHERE condition can also all be used after the addition HAVING, and sometimes in the ON condition of a Join expression after the addition FROM.
  • If the database table is accessed with generic SAP buffering, the buffered area must be fully specified in the WHERE condition, otherwise buffering is ignored.
  • If the database tables are accessed using single record buffering, the conditions joined using ANDin the WHERE condition must be specified for all key fields of the primary key, otherwise buffering is ignored.
