Problem IT08280
|
Status: Closed |
CLI APPLICATION USING CHAINING WITH INSERT BUFFERING MAY GET SQL_SUCCESS BUT SQLROWCOUNT() GIVES 0. |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
An application that is using CLI insert buffering with chaining
to insert the rows more than once on the same statement handle
will receive the SQL_SUCCESS when settiing SQL_ATTR_CHAINING_END
to end the chain. But SQLRowCount() will return 0 saying no rows
inserted.
Steps to reproduce problem :
==========================
opt echo on
opt callerror on
quickc 1 1 sample
sqlallocstmt 1 1
sqlsetstmtattr 1 SQL_ATTR_INSERT_BUFFERING
SQL_ATTR_INSERT_BUFFERING_IGD
sqlexecdirect 1 "create table tab1(id char(10) unique not null)"
-3
sqlexecdirect 1 "insert into tab1 (id) values ('001')" -3
sqlprepare 1 "insert into tab1 (id) values (?)" SQL_NTS
getmem 1 1 SQL_C_CHAR 30
sqlbindparameter 1 1 SQL_PARAM_INPUT SQL_C_CHAR SQL_VARCHAR 30 0
1
sqlsetstmtattr 1 SQL_ATTR_CHAINING_BEGIN 1
updatemem 1 sql_c_char value SQL_NTS "001"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "001" ### duplicate
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "001" ### duplicate
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "001" ### duplicate
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "001" ### duplicate
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "001" ### duplicate
sqlexecute 1
sqlsetstmtattr 1 SQL_ATTR_CHAINING_END 1
sqlrowcount 1
sqlbindparameter 1 1 SQL_PARAM_INPUT SQL_C_CHAR SQL_VARCHAR 30 0
1
updatemem 1 sql_c_char value SQL_NTS "003"
sqlexecute 1
sqlbindparameter 1 1 SQL_PARAM_INPUT SQL_C_CHAR SQL_VARCHAR 30 0
1
sqlsetstmtattr 1 SQL_ATTR_CHAINING_BEGIN 1
updatemem 1 sql_c_char value SQL_NTS "002"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "004"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "005"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "006"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "007"
sqlexecute 1
updatemem 1 sql_c_char value SQL_NTS "008"
sqlexecute 1
sqlsetstmtattr 1 SQL_ATTR_CHAINING_END 1
sqlrowcount 1
sqltransact 1 1 sql_rollback
sqlfreestmt 1 sql_drop
killenv 1
In the above case, first SQL_ATTR_CHAINING_END will fail because
all the rows are duplicate and returns the SQLRowCount as
0.(Value returned here depends on the number of rows
successfully inserted)
But during the 2nd chaining all the rows are good rows, so
SQL_ATTR_CHAINING_END should receives SQL_SUCCESS with correct
row count. Instead SQLRowCount() API is returning 0 or incorrect
result. |
