In clause

Identifies tables in any external database to which the Microsoft Access database engine can connect, such as a dBASE or Paradox database or an external Microsoft Access database.

Syntax

To identify a destination table:

[SELECT | INSERT] INTO destination IN
{path | ["path" "type"] | ["" [type; DATABASE = path]]}

To identify a source table:

FROM tableexpression IN
{path | ["path" "type"] | ["" [type; DATABASE = path]]}

A SELECT statement containing an IN clause has these parts:

Part	Descri ption
destination	The name of the external table into which data is inserted.
tableexpression	The name of the table or tables from which data is retrieved. This argument can be a single table name, a saved query, or a compound resulting from an INNER JOIN, LEFT JOIN, or RIGHT JOIN.
path	The full path for the directory or file containing table.
type	The name of the database type used to create table if a database is not a Microsoft Access database (for example, dBASE III, dBASE IV, Paradox 3.x, or Paradox 4.x).

Remarks

You can use IN to connect to only one external database at a time.

In some cases, the path argument refers to the directory containing the database files. For example, when working with dBASE, Microsoft FoxPro, or Paradox database tables, the path argument specifies the directory containing .dbf or .db files. The table file name is derived from the destination or tableexpression argument.

To specify a non-Microsoft Access database, append a semicolon (;) to the name, and enclose it in single (' ') or double (" ") quotation marks. For example, either 'dBASE IV;' or "dBASE IV;" is acceptable.

You can also use the DATABASE reserved word to specify the external database. For example, the following lines specify the same table:

... FROM Table IN "" [dBASE IV; DATABASE=C:\DBASE\DATA\SALES;];

... FROM Table IN "C:\DBASE\DATA\SALES" "dBASE IV;"

Notes: 

• For improved performance and ease of use, use a linked table instead of IN.

• You can also use the IN reserved word as a comparison operator in an expression.
