This chapter details the ODBC functionality that FairCom DB SQL supports through the ODBC Driver.
General ODBC and SQL Support Levels
The FairCom ODBC Drivers available with FairCom DB V12 (including FairCom RTG V3 and FairCom Edge V3) are compliant with ODBC V3.52.
ODBC specifies general conformance levels in two areas:
- ODBC application programming interface (API). FairCom DB SQL supports all Core and Level 1 ODBC API functions, and most Level 2 functions.
- ODBC SQL syntax. FairCom DB SQL supports Extended SQL syntax.
The rest of this chapter provides more detail on that support. Specifically, it details the information the FairCom DB ODBC driver returns when applications call the following functions:
- SQLGetInfo() returns various details about the driver and its data source
- Environment, connection, and statement attribute functions return or specify attributes of driver behavior
- SQLGetFunctions() returns ODBC functions the driver supports
- SQLGetTypeInfo() returns data types the driver supports
Responses to SQLGetInfo
Applications call the SQLGetInfo() function to retrieve details about support for a specific driver and data source provided for different ODBC functionality.
Applications supply the InfoType argument to SQLGetInfo() to specify what information type they seek. SQLGetInfo() returns the information to the InfoValuePtr output argument. The following table lists each InfoType argument the ODBC Driver recognizes along with the associated value returned to SQLGetInfo(). Shaded rows indicate information types renamed or deprecated for ODBC 3.0
For more detail about the SQLGetInfo() function see the Microsoft ODBC Programmer's Reference.

Supported Functions
The c-treeSQL ODBC Driver supports all Core and Level 1 API functions, and most Level 2 functions. Here is a complete list of the functions the driver supports. Applications can request this same information through the SQLGetFunctions() function with a FunctionId of SQL_API_ODBC3_ALL_FUNCTIONS.
SQLAllocConnect()
(Deprecated in ODBC 3.0)
SQLAllocEnv()
(Deprecated in ODBC 3.0)
SQLAllocHandle()
SQLAllocStmt()
(Deprecated in ODBC 3.0)
SQLBindCol()
SQLBindParam()
(Deprecated in ODBC 3.0)
SQLBindParameter()
Binds a buffer to a parameter marker in a SQL statement. SQLBindParameter() has 10 parameters. Parameter 4 and 5 change the way the date field is handled with reference to TPE_DFLT_DATE.
- ValueType [Input] The C date type of the parameter
- ParameterType [Input] The SQL data type of the parameter
When date is specified using a character string by setting ValueType to SQL_C_CHAR, the C data type of the parameter, the date formats supported are as follows:
When ParameterType is set to SQL_CHAR and TPE_DFLT_DATE is set to ISO_DFLT_DATE, the date formats supported is only YYYY-MM-DD and also the same format with ‘/’ as separator.
When ParameterType is set to SQL_TYPE_DATE and TPE_DFLT_DATE is set to ISO_DFLT_DATE, the date formats supported are MM-DD-YYYY, YYYY-MM-DD and DD-MON-YYYY and also the same formats with ‘/’ as the separator.

Supported Data Types
FairCom DB SQL supports a set of data types that the FairCom DB ODBC Driver maps to corresponding ODBC SQL data types. The following table lists the FairCom DB SQL data types and the corresponding ODBC data types.
c-treeSQL ODBC and Corresponding ODBC Data Types
| FairCom DB ODBC Data Type | ODBC Data Type |
|---|---|
| BIGINT | SQL_BIGINT |
| BINARY | SQL_BINARY |
| BIT | SQL_BIT |
| CHAR or CHARACTER | SQL_CHAR |
| DATE | SQL_DATE |
| DECIMAL | SQL_DECIMAL |
| DOUBLE PRECISION | SQL_DOUBLE |
| FLOAT | SQL_FLOAT |
| INTEGER | SQL_INTEGER |
| LVARBINARY | SQL_LONGVARBINARY |
| LVARCHAR | SQL_LONGVARCHAR |
| MONEY | SQL_NUMERIC |
| NUMERIC | SQL_NUMERIC |
| REAL | SQL_REAL |

| TINYINT | SQL_TINYINT |
| VARBINARY | SQL_VARBINARY |
| VARCHAR | SQL_VARCHAR |
Thread Safety of FairCom DB ODBC Driver
By default, the FairCom DB ODBC Driver is thread-safe. However, this may not always be desired as it involves overhead on the performance of the system. Single threaded ODBC applications do not require thread safety as only one thread is involved.
To disable the thread safety feature, the following runtime flag is used:
DH_DISABLE_ODBC_THREAD_SAFETY
This flag must be set in dhsql.ini for FairCom DB SQL on Windows NT. In Unix, it will be an environment variable in the setup file.
By default, the thread safety feature is enabled. To disable this feature, set:
DH_DISABLE_ODBC_THREAD_SAFETY = Y
ODBC Error Messages
General SQL error messages and ODBC Driver-specific errors are documented online in the Error Code Reference. Aside from the SQL error messages, there is another known error that may occur when using FairCom DB ODBC Driver with Crystal Reports. This error may occur when generating reports that require a left outer join between tables. The cause of this error is due to the syntax used by Crystal Reports when creating the SQL statement. Users can specify the proper syntax to use by changing a key in the Windows registry. For more information about how to change the registry, please refer to this document: How to Resolve the Join Syntax Errors in Crystal Reports 9. Or search the SAP Community Network for: Crystal left outer registry.
