Syntax
Remarks
Example

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 engine database.

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

Description

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 engine database (for example, dBASE III, dBASE IV, Paradox 3.x, or Paradox 4.x).

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 engine 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;"
NoteNote
  • 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. For more information, see the In operator.

The following table shows how you can use the IN clause to retrieve data from an external database. In each example, assume the hypothetical Customers table is stored in an external database.

External database

SQL statement

Microsoft® Access atabase engine database

SELECT CustomerID
FROM Customers
IN OtherDB.mdb 
WHERE CustomerID Like "A*";

dBASE III or IV. To retrieve data from a dBASE III table, substitute "dBASE III;" for "dBASE IV;".

SELECT CustomerID
FROM Customer
IN "C:\DBASE\DATA\SALES" "dBASE IV;"
WHERE CustomerID Like "A*";

dBASE III or IV using Database syntax.

SELECT CustomerID
FROM Customer
IN "" [dBASE IV; Database=C:\DBASE\DATA\SALES;] 
WHERE CustomerID Like "A*";

Paradox 3.x or 4.x. To retrieve data from a Paradox version 3.x table, substitute "Paradox 3.x;" for "Paradox 4.x;".

SELECT CustomerID
FROM Customer
IN "C:\PARADOX\DATA\SALES" "Paradox 4.x;"
WHERE CustomerID Like "A*";

Paradox 3.x or 4.x using Database syntax

SELECT CustomerID
FROM Customer
IN "" [Paradox 4.x;Database=C:\PARADOX\DATA\SALES;] 
WHERE CustomerID Like "A*";

A Microsoft Excel worksheet

SELECT CustomerID, CompanyName
FROM [Customers$] 
IN "c:\documents\xldata.xls" "EXCEL 5.0;"
WHERE CustomerID Like "A*"
ORDER BY CustomerID;

A named range in a worksheet


SELECT CustomerID, CompanyName
FROM CustomersRange
IN "c:\documents\xldata.xls" "EXCEL 5.0;"
WHERE CustomerID Like "A*"
ORDER BY CustomerID;
