Migrating client variable data
To migrate your client variable data to another data source, you should know the structure of the
database tables that store this information. Client variables stored externally use two simple
database tables, like those shown in the following tables:
CDATA Table
Column Data type
cfid CHAR(64), TEXT, VARCHAR, or equivalent
app CHAR(64), TEXT, VARCHAR, or equivalent
data MEMO, LONGTEXT, LONG VARCHAR, or equivalent
CGLOBAL Table
Column Data type
cfid CHAR(64), TEXT, VARCHAR, or equivalent
data MEMO, LONGTEXT, LONG VARCHAR, or equivalent
lvisit TIMESTAMP, DATETIME, DATE, or equivalent
Creating client variable tables
Use the following sample ColdFusion page as a model for creating client variable database tables
in your own database. However, keep in mind that not all databases support the same column
data type names. For the proper data type, see your database documentation.
Tip: The ColdFusion MX Administrator can create client variable tables for data sources that use
bundled JDBC drivers. For more information, see the online Help.
Sample table creation page
<!---- Create the Client variable storage tables in a datasource.
This example applies to Microsoft Access databases --->
<cfquery name="data1" datasource="#DSN#">
CREATE TABLE CDATA
(
cfid char(20),
app char(64),
data memo
)
</cfquery>
<cfquery name="data2" datasource="#DSN#">
CREATE UNIQUE INDEX id1
ON CDATA (cfid,app)
</cfquery>
<cfquery name="global1" datasource="#DSN#">
CREATE TABLE CGLOBAL
(
cfid char(20),
data memo,
lvisit date
