To join rows, select columns in both tables whose values and data types
match. You should:
1. Highlight a column name from each list in the Source Columns area.
The first highlighted column in the top list pairs with the first
highlighted column in the bottom list, the second columns are paired,
and so on. Rows join only if values and data types match for all the
column pairs.
2. Click Match. The selected pair of columns appears in the Match
columns box. Matching columns do not have to have the same names
and do not have to be in the same relative column position in both
tables.
3. (Optional) To only include the first match found, check the boxes
associated with Drop multiples in both tables. Only the first match
found is written to the new table. If you specify this option for one table,
the first match value is joined with all matches in the other table. If you
do not check the boxes associated with Drop multiples in either table, a
Cartesian join is performed within each group of matching column
values.
4. (Optional) To include all rows from the data table, even when there is no
matching value, check the boxes associated with Include non-matches.
You can specify this option for either or both data tables being joined.
Joins the two tables side by side.
Joins two tables using a Cartesian fashion, where it forms a new table
consisting of all possible combinations of the rows from two original tables.
JMP crosses the data in the first table with the data in the second to display
all combinations of the values in each set.
Select the Select Columns for joined table option if you want to select a
subset of columns from either table for inclusion in the output table. Follow
these steps:
1. In the Source Columns area, highlight the columns from each table that
you want to include in the new table.
2. Click Select in the Output Columns area.
To give a name to the joined table, type a name in the box beside Output
table name.
