Check if column X exists in table Y

Question

I have two string variables:

• lv_table_name contains a table name
• lv_column_name contains a column name

Is there a way to check if there is a table (or view) which has the given column?

Answer 1

You can find table and view definitions in table DD03L. If you can access the table with your mentioned combination table/column it will be noticably faster.

REPORT.

DATA: lv_column_name TYPE string VALUE 'MY_FIELD'.

"this will tell you which tables/views exist containing the column 'MY_FIELD'
SELECT tabname
  FROM dd03l INTO TABLE @DATA(lt_tables)
  WHERE fieldname EQ @lv_column_name.

Answer 2

For Netweaver 7.5, you can use a simple OPEN SQL select on DD03L https://help.sap.com/doc/abapdocu_750_index_htm/7.50/en-US/abensql_expr_literal_abexa.htm

SELECT SINGLE @abap_true
       FROM DD03L
       WHERE tabname EQ @lv_table_name AND fieldname EQ @lv_column_name
       INTO @DATA(lv_exists).
