UniBasic Commands Reference - Rocket Software

Normally you specify data.type as SQL.B.BASIC. If you specify sql.type as
SQL.DATE, however, you can specify data.type as SQL.B.INTDATE; if you specify
sql.type as SQL.TIME, you can specify data.type as SQL.B.INTTIME. If you specify
sql.type as SQL.BINARY, SQL.VARBINARY, or SQL.LONGVARBINARY, you
can specify data.type as SQL.B.BINARY.
If you use SQL.B.INTDATE, the UniData BCI assumes the program variable holds
a date in UniData internal date format and uses the DATEFORM conversion string
to convert the internal date to an external format as required by the data source. To
set or change the DATEFORM conversion string, see the SQLSetConnectOption
function.
If you specify sql.type as SQL.TIME and data.type as SQL.B.INTTIME, UniData
BCI assumes the program variable holds a time in UniData internal time format and
does not convert the data.
SQLBindParameter uses the value of prec only for the following SQL data types:
SQL.CHAR
SQL.VARCHAR
SQL.LONGVARCHAR
SQL.WCHAR
SQL.WVARCHAR
SQL.WLONGVARCHAR
SQL.BINARY
SQL.VARBINARY
SQL.LONGVARBINARY

For all other data types, the extended parameters DBLPREC, FLOATPREC, and
INTPREC determine the maximum length for strings representing double-precision
numbers, floating-point numbers, and integers.
