When the HCL
OneDB™ product uses a
display format to read a date string, the field specification defines the number of characters to
expect as input.
This field specification has the following syntax.Figure 1: Format qualifiers for reads
Element
Description
- (minus sign)
Field value is left-aligned and begins with a digit; this value
can include trailing spaces.
0 (zero)
Field value is right-aligned; any zeros on the left are pad characters
that are not significant.
max_width
Integer that indicates the maximum number of characters to read.
min_width
Integer that indicates the minimum number of characters to read.
The first character of the field specification indicates
whether to assume that the field value is justified or padded. If
the first character is not a minus sign or a zero, the HCL
OneDB product
assumes that the field value is right-aligned and any spaces on the
left are pad characters.
If the field value begins with a zero,
however, it cannot include pad characters.
The HCL
OneDB product ignores the field
specification if the field value is not a numeric value.
