Informix ESQL/C functions

In a DataBlade API module, you can use some of the functions in the IBM® Informix® ESQL/C library functions to perform conversions and operations on different data types. The Informix ESQL/C functions do not begin with the mi_ prefix. Various header files declare these functions.

For more information, see ESQL/C header files.

The functions of the Informix ESQL/C function library that are valid in a DataBlade API module can be divided into the following categories.

Category of DataBlade API function	More information
Byte handling	Manipulate byte data
Character processing	ESQL/C functions for string conversion Operations on character values
DECIMAL-type and MONEY-type processing	ESQL/C functions for decimal conversion Perform operations on decimal data
DATE-type processing	ESQL/C functions for date conversion Operations on date data
DATETIME-type processing and INTERVAL-type processing	ESQL/C functions for date, time, and interval conversion Operations on date and time data
INT8-byte processing	Convert INT8 values Perform operations on eight-byte values
Processing for other C-language data types	Format numeric strings

For a complete list of Informix ESQL/C functions in each of these categories, see the IBM Informix DataBlade API Function Reference, which provides descriptions of these public functions, in alphabetical order.
