Use @STRNUM
to convert a number into a string and specify the output format and padding.
Syntax
@STRNUM (field, {LEFT | LEFTSPACE | RIGHT | RIGHTZERO} [length])
field
The name of the source numeric field.
LEFT
Left justify, fill the rest of the target column with spaces
LEFTSPACE
Left justify, fill the rest of the target column.
RIGHT
Right justify, fill with spaces
RIGHTZERO
Right justify, fill the rest of the target column with zeros
length
Specifies the output length, when any of the options are used that specify padding (all but LEFT
).
Example
If field NUM
has the value 15 and the target column CHAR1
is a maximum of 5 characters, the following examples show the different types of results obtained with formatting options.
Function statement | Results (- denotes a space) |
---|---|
CHAR1 = @STRNUM (NUM, LEFT) |
15 |
CHAR1 = @STRNUM (NUM, LEFTSPACE) |
15--- |
CHAR1 = @STRNUM (NUM, RIGHTZERO) |
00015 |
CHAR1 = @STRNUM (NUM, RIGHT) |
---15 |
If an output length
of 4 is specified in the preceding example, the following shows the different types of results.
Function statement | Results (- denotes a space) |
---|---|
CHAR1 = @STRNUM (NUM, LEFTSPACE, 4) |
15-- |
CHAR1 = @STRNUM (NUM, RIGHTZERO, 4) |
0015 |
CHAR1 = @STRNUM (NUM, RIGHT, 4) |
--15 |
