Type conversion function
Adaptive Server provides three data type conversion functions: Convert, INTTOHEX, and HEXTOINT.
The syntax of the convert () function:
Convert (DataType, Expression [, style])
This function can be used in the Select selection list, where the WHERE clause, and any place to exist in the expression.
Select Name, Convert (Char (8), SALARY) "Yuan"
From auths
WHERE SALY> 200
result:
Name
Xu Lingyan ??? 280.50 yuan
Zhang ???? 550.00 yuan
?
The style parameter in the Convert function provides multiple date display formats for DateTime or SmallDateTime to CHAR or VARCHAR. Style's digital parameters determine how the date is displayed. The year can be displayed as a two-digit (yy), or it can be displayed in 4 digits (YYY). For example, assigning a Style parameter to 100, you can get a 4-bit annual number, that is, a century value (YYY).
The following table lists the available values of the style parameter and the various date formats that can be used. When using the STYLE parameter together with the SmallDateTime type, those formats including seconds and milliseconds will be displayed in their bit value.
