Code Inspection: Duplicating column name in SELECT

Reports duplicated names of column aliases in SELECT lists.

Example (Sybase ASE):

CREATE TABLE t1 (a TEXT, b INT, c INT); SELECT a AS x, b AS x FROM t1;

The x alias name is used for a and b columns. These assignments are highlighted as errors because you cannot use identical alias names for columns in Sybase ASE.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
