BUG: Syntax Error When Using Qualified Table Name with Quotes

SYMPTOMS

When using table names qualified with the current qualifier and using identifier quote character to enclose the current qualifier and the table name, you receive a syntax error. This happens with dBASE, Paradox, Microsoft FoxPro, Btrieve, Microsoft Excel, and Text Open Database Connectivity (ODBC) drivers. It does NOT happen with the Microsoft Access driver.

For example, in case of dBase driver, if the values returned by SQLGetConnectOption and SQLGetInfo are as shown:

 SQLGetConnectOption(hdbc,SQL_CURRENT_QUALIFIER,pvParam)
      Returns "C:\Database"
 SQLGetInfo(hdbc, SQL_IDENTIFIER_QUOTE_CHAR, rgbInfoValue,cbInfoValueMax)
      Returns "`"
 SQLGetInfo(hdbc, SQL_QUALIFIER_NAME_SEPARATOR,rgbInfoValue,cbInfoValueMax)
      Returns "\"
				

Then you let a table called testtable exist in the data source. The queries of the form below will receive syntax error SQLState=37000, szErrorMsg=, when executed using SQLExecDirect or SQLExecute calls.

   Select * from 'C:\Database'\'testtable'
   delete from 'C:\Database'\'testtable'
   Update 'C:\Database'\'testtable' set <colname>=<new value>
				

If you do not use the quote character around the qualifier and the table, these queries work fine.
