The QUERY HEADER clause specifies the column header that SQL uses in displays of result tables that contain that column. If you include the QUERY HEADER clause, SQL uses the query header as the column header. If you omit the clause, SQL uses the column name as the column header. The column header can include any character except a carriage return, a line feed, or a control character. To include a double quotation mark in a column header, enclose it in single quotation marks. The following example defines a query header for one column and a DATATRIEVE query name for another column: SQL> ALTER TABLE TEMP cont> ADD STATE CHAR (2) cont> QUERY NAME FOR DATATRIEVE IS 'ST' cont> ADD SEX CHAR (1) cont> QUERY HEADER IS 'S'/'E'/'X'; These statements define query headers and query names for the STATE and SEX columns. The slash character (/) specifies that the header is split into three lines, so the header for the SEX column is 1 character wide, like the column itself. Both SQL and DATATRIEVE display the query header used in this example. Only DATATRIEVE recognizes the query name.
