Supported Data Types for SQL Server

The table below shows the mappings used by Acu4GL when interacting with Microsoft SQL Server.

Data type	Generated using...
DATETIME	The DATE XFD directive, specifying both date and time information.
DATE	The DATE XFD directive, specifying only date information.
TIME	The DATE XFD directive, specifying only time information.
BINARY(`n`)	The BINARY XFD directive, specifying a COBOL field 8000 bytes or less. `n` refers to the number of bytes.
IMAGE	The BINARY XFD directive, specifying a COBOL field greater than 8000 bytes.
CHAR(`n`) or NCHAR(`n`)	A COBOL field of type PIC X(`n`), where `n` is less than 8000 characters/digits. Notes for NCHAR: The Unicode and COBOL conversion is also dependent on the COBOL_CHARACTER_SET configuration variable When using an NCHAR data type in your database, the UNICODE data is translated to the character set specified by COBOL-CHARACTER-SET when read, and vice versa when written
GUID	A COBOL field of type PIC X(36). Note: Support is only for existing tables containing this type; Acu4GL cannot create a new column of this type. If required, use the A_MSSQL_IGNORE_GUID_COLUMNS configuration variable to ignore the GUID column in a table.
TEXT	A COBOL field of type PIC X(`n`), where `n` is 8000 characters/digits or more.
VARCHAR(`n`) or NVARCHAR(`n`)	The VAR_LENGTH XFD directive and specifying a COBOL field of type PIC X(`n`), where `n` refers to the size of the COBOL field. For NVARCHAR, the Unicode and COBOL conversion is also dependent on the COBOL_CHARACTER_SET configuration variable.
FLOAT	A COBOL field of type DOUBLE.
REAL	A COBOL field of type FLOAT.
TINYINT	A COBOL field of type PIC 9 or PIC 99.
SMALLINT	A COBOL field of type PIC 9(3) or PIC 9(4).
INT	A COBOL field of type of PIC 9(5) to PIC 9(8).
BIGINT	A COBOL field of type PIC 9(9) to PIC 9(18).
DECIMAL(`n`,0)	A COBOL field of type PIC(19) or larger, where `n` is the number of digits.
DECIMAL(`n`,`m`)	A decimal COBOL field, where `n` refers to the number of digits to the left of the decimal point and `m` refers to the number of digits to the right of the decimal point.
