SYMPTOMS

When you use the "oj" outer join syntax with a parameter in a SELECT statement using the Microsoft SQL Server driver with a SQL Server 6.5 back end, the following error message is returned:
"[Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error"

CAUSE

The problem occurs when the driver removes ODBC escape characters from the query.

MORE INFORMATION

Steps to Reproduce Behavior

  1. Create the following tables on a SQL Server 6.5 back end:
    create table t1(c1 int, c2 int)
    create table t2(c1 int, c2 int)
    					
  2. Paste the following code in a Microsoft Visual C++ console application:
    #include <windows.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <stdio.h>
    #include <sql.h>
    #include <sqlext.h>
    
    void main(void)
    {
       	SQLHANDLE henv;
       	SQLHANDLE hdbc;
       	SQLHANDLE hstmt;
       	RETCODE rc;
    
       	char Statement[100] = {"select * from {oj t1 left outer join t2 on t1.c1=t2.c2} where t1.c1=?"};
       	char dsn[10] = {"YourDSNName"};
       	char user[5] = {"YourUserName"};
       	char pass[7] = {"YourPassword"};
    	int param =1;
       	long sqlnts = SQL_NTS;
       	long m_bytesRet = SQL_NTS;   	
    	long cbOparm = 0;
       	
    	rc = SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv);
    	rc = SQLSetEnvAttr(henv,SQL_ATTR_ODBC_VERSION,(SQLPOINTER)SQL_OV_ODBC3, SQL_IS_UINTEGER);
    	rc = SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc);
    	rc = SQLConnect(hdbc, (SQLCHAR *)dsn, SQL_NTS, (SQLCHAR *) user,SQL_NTS,(SQLCHAR *) pass, SQL_NTS);
    	rc = SQLAllocHandle(SQL_HANDLE_STMT,hdbc,&hstmt);  	
    	rc = SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_SLONG,SQL_INTEGER, 0, 0,&param, 0, &cbOparm);	
    	rc = SQLPrepare(hstmt, (SQLCHAR *)Statement, SQL_NTS);
    	rc = SQLExecute(hstmt);
    
        // Variables for SQLDiagRec.  
        char mstate[6] = "\0";
        long native = 0;
        char mtext[300] = "\0";
        short mlength = 0;
        short i = 0;
    
        while ((rc = SQLGetDiagRec(SQL_HANDLE_STMT, hstmt, ++i, (unsigned char*)&mstate, &native, (unsigned char*)&mtext,300,&mlength))!=SQL_NO_DATA)
        printf("\nODBC Error:\t%s\n",mtext);
    }
    					
  3. Change the data source name, user id, and password.
  4. Compile and then run the code.
