OP Selection to array

version 1.5

OP Selection to array (connectionID; bindID{; tableID}) Longint

Parameter	Type		Description
connectionID	Longint		Connection ID with target server
bindID	Longint		Bind list ID
tableID	Longint		Number of the table in the database
Function result	Longint		Error code result for the function

OP Selection to array places the server fields into arrays. Both the server fields and the arrays are defined in bindID by using OP Define bind by pointer and/or OP Define bind by numbers.

Using OP Selection to array, you can retrieve data from a single target table, or you can retrieve data from a target table and its related tables. To retrieve data from a target file and its related tables:

• The target table must be a Many table and the related table must be a One table.

• The relation must be automatic.

• The tables/fields to be retrieved from the target table and the related table must be in the same bind list.

tableID is the table number of the target table. If you omit this parameter or pass 0, the table number of the first table/field couple in the bind list is used as the target table.

Consider the following structure:

Suppose you want to retrieve the [Invoices]Invoice ID, [Invoices]Invoice Date, [Invoices]Invoice Total, [Customers]Company, and [Customers]City fields, in this order. You retrieve fields from the two tables using a relation, so the target table must be the Many table, in this case [Invoices]. Because the first field is from this table, you just need to build the bind appropriately, and you can omit the target table.

Suppose you want to retrieve the [Customers]Company and [Customers]City fields based on the selection in the [Invoices] table. You need to build the bind appropriately, and you have to pass [Invoices] as the target table. Here, you do not retrieve fields from the [Invoices] table even though you use it as the target table.

If OP Selection to array executes successfully, it returns 0. Otherwise, this function returns one of the following errors:

Error Code	Description
-108	Not enough memory to perform this operation.
-9969	Invalid field type requested.
-9971	Field number is out of range.
-9972	Table number is out of range.
10128	The 4D Open for 4th Dimension package has not been initialized.
10135	Invalid parameter type.
10136	The connection does not exist.
10137	The context does not exist.
10139	The context is not defined.
10153	Unable to convert this type of data.
