Re: Alter Table - Error

Hi Sri,

Altering data type of a column is supported only if it is a COLUMN store table.

I tried the following

SET schema sreehariv;

create columntable"TIME_TEST_COL" ("CRTIME"DATE);

create table"TIME_TEST_ROW" ("CRTIME"DATE);

insert into"TIME_TEST_COL"values(CURRENT_DATE);

insert into"TIME_TEST_ROW"values(CURRENT_DATE);

ALTER TABLE"TIME_TEST_ROW"ALTER ("CRTIME"TIMESTAMP);

{

Could not execute 'ALTER TABLE "TIME_TEST_ROW" ALTER ("CRTIME" TIMESTAMP)' in 392 ms 612 µs .

SAP DBTech JDBC: [7] (at 35): feature not supported: cannot modify data type of column: CRTIME: line 1 col 36 (at pos 35)

}

ALTER TABLE"TIME_TEST_COL"ALTER ("CRTIME"TIMESTAMP);

Where, the row store table could not be altered .
