Sharing data with other Windows applications

When retrieving data from log files, you will likely want the tag
names—not the tag index. Therefore, you have to retrieve data from
more than one table. To do this, you have to join tables. When you join
tables, you connect one or more fields in the tables. These fields must
have the same name and must contain the same type of data.
1. Join the TTagindex field in the tag name field list to the Tagindex
field in the other list.
2. Select the fields in the floating point or string list that you want
data for. You can select the fields in any order.
To select fields, double–click them. The data for that field will
appear in the Query spreadsheet.
When you drag
TTagindex from one
table to the
equivalent field in
the other table, a join
is formed.
