Queries involving where clause with timestamp data type

Question

I need to use milliseconds in my tables and do queries where I compare the time in the table to a specific time. I changed the column to the TIMESTAMP data type (from DATE) to accommodate the milliseconds.
I am accessing the data via a C++ program using ODBC to access the Oracle 10g XE database and a SQLBindParameter statement to set up the comparisons.
Below is a table that looks like mine but simplified to just a few fields:
. DATA_ID NOT NULL NUMBER(10)
. START_TIME NOT NULL TIMESTAMP(6)
. STOP_TIME NOT NULL TIMESTAMP(6)
My query is:
. string sql("select "\
. "to_Char(rv.start_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "to_Char(rv.stop_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "rv.data_id "\
. "from "\
. "Reservation rv "\
. "where "\
. "rv.data_id = ? and "\
. "rv.stop_time >= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3') and "\
. "rv.start_time <= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3');");
MY C++ code (minus the usual statement preparation material) is:
. string startTime("20090826 15:42:02.000");
. string stopTime("20110828 02:04:52.000");
. SQLRETURN rc = SQL_SUCCESS;
. SQLINTEGER sqlRsrcInstanceId = resource->getResourceInstanceId();
. SQLLEN sqlRsrcInstanceIdLI = 0;
. rc |= SQLBindParameter( stmtHandle, 1, SQL_PARAM_INPUT,
. SQL_C_LONG, SQL_INTEGER, 0, 0,
. &sqlRsrcInstanceId, 0, &sqlRsrcInstanceIdLI );
. SQLCHAR sqlStartTime[24];
. memset(sqlStartTime, 0, 24);
. SQLLEN sqlStartTimeLI = SQL_NTS;
. strncpy( (char*)sqlStartTime, startTime, 23);
. rc |= SQLBindParameter( stmtHandle, 2, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStartTime)-1, 0,
. &sqlStartTime, sizeof(sqlStartTime)-1,
. &sqlStartTimeLI);
. SQLCHAR sqlStopTime[24];
. memset(sqlStopTime, 0, 24);
. SQLLEN sqlStopTimeLI = SQL_NTS;
. strncpy( (char*)sqlStopTime, stopTime, 23);
. rc |= SQLBindParameter( stmtHandle, 3, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStopTime)-1, 0,
. &sqlStopTime, sizeof(sqlStopTime)-1,
. &sqlStopTimeLI);
When the statement is executed, I get the following error:
. ODBC Return Code: SQL Error.
. Native Error Code/Message:
. 932/[Oracle][ODBC][Ora]ORA-00932: inconsistent datatypes: expected - got -
Any suggestions on what is wrong or a better way to perform the query?

Answer 1

The only way to test a query is to get out of your environment and fire up SQL*Plus (command line).
I can not read all of what you wrote but the error you are generating should show up there along with sufficient information to quickly fix it.
Once you have working statement put it back into your environment.
