Rules and Guidelines for Microsoft SQL Server

Rules and Guidelines for Microsoft SQL Server

Consider the following rules and guidelines when you configure ODBC connectivity to a Microsoft SQL Server database on Windows:
  • If you want to use a Microsoft SQL Server connection without using a Data Source Name (DSN less connection), you must configure the odbcinst.ini environment variable.
  • If you are using a DSN connection, you must add the entry "EnableQuotedIdentifiers=1" to the ODBC DSN. If you do not add the entry, data preview and mapping run fail.
  • When you use a DSN connection, you can configure the DataDirect specific properties. For more information about how to configure and use the Data Direct specific properties, see the DataDirect documentation.
  • You can use the Microsoft SQL Server NTLM authentication on a DSN less Microsoft SQL Server connection on the Microsoft Windows platform.
  • If the Microsoft SQL Server table contains a UUID data type and if you are reading data from an SQL table and writing data to a flat file, the data format might not be consistent between the OLE DB and ODBC connection types.
  • You cannot use SSL connection on a DSN less connection. If you want to use SSL, you must use the DSN connection. Enable the Use DSN option and configure the SSL options in the odbc.ini file.
  • If the Microsoft SQL Server uses Kerberos authentication, you must set the GSSClient property to point to the Informatica Kerberos libraries. Use the following path and filename:
    <Informatica installation directory>/server/bin/libgssapi_krb5.so.2.
    Create an entry for the GSSClient property in the DSN entries section in
    odbc.ini
    for a DSN connection or in the SQL Server wire protocol section in
    odbcinst.ini
    for a connection that does not use DSN.
  • If you use the DataDirect ODBC driver to connect to Microsoft SQL Server, the Decimal data rounds off within the target database based on the scale values in the database tables. For example, if the scale is 5, the target Decimal data round-off occurs after the fifth digit that follows the decimal point. When the scale is 5, the input value 12.3456789 rounds off to a target Decimal value of 12.34568.
  • If you use Microsoft SQL Sever Native client to configure native connectivity to Microsoft SQL Server databases, the Decimal data truncates based on the specified scale in the target database tables. For example, if the scale is 5, the Decimal data truncation occurs after the fifth digit that follows the decimal point. When the scale is 5, the input value 12.3456789 truncates to a target Decimal value of 12.34567.
