world.DatabaseColumnType

MUSHclient script function (Method) — introduced in version 4.40

Returns the type of data in an SQL column

Prototype

long DatabaseColumnType(BSTR DbName, long Column);

You can use this, after successfully doing a DatabaseStep, to find the type of data actually in each column of the current row.

Data types are:

Integer: 1
Float: 2
Text: 3
Blob: 4
Null: 5

This can be called after DatabaseStep to find whether a particular column is text, a number, or NULL (no data).

Columns start at 1 for the first column, up to the number returned by DatabaseColumns.

t = DatabaseColumnType ("db", 2)  --> 3 (if the column is text)

A positive integer representing the data type of the specified column, as follows:

Integer: 1
Float: 2
Text: 3
Blob: 4
Null: 5

Otherwise, an error code:

-1 : Database id not found
-2 : Database not open
-4 : Do not have prepared statement
-5 : Do not have a valid row
-7 : Column number out of range
