Status: Closed |
EXPLAINING AN SQL STATEMENT ACCESSING COLUMN-ORGANIZED TABLES IN"RECOMMEND INDEXES" EXPLAIN MODE CAN RESULT IN SQL0901N |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
When explaining an SQL statement that accesses a
column-organized table in "RECOMMEND INDEXES" explain mode, a
SQL0901N error message with reason "Column number out of range"
can be returned. Indexes are not supported on column-organized
tables but a SQL0217W warning should be returned instead of the
SQL0901N error along with no index recommendation.
Example :
db2 "CREATE TABLE CO (F1 INTEGER) ORGANIZE BY COLUMN"
DB20000I The SQL command completed successfully.
$ db2 SET CURRENT EXPLAIN MODE RECOMMEND INDEXES
DB20000I The SQL command completed successfully.
$ db2 "SELECT F1 FROM CO WHERE F1=1"
SQL0901N The SQL statement or command failed because of a
database system
error. (Reason "column number out of range".) SQLSTATE=58004 |
