This example demonstrates the use of the OR operator, to search for multiple entries in a single column.
TYPE == fault || TYPE == shear
Select Query
Data from the toolbar or the Analysis menu.
Create the Expression TYPE == fault.
Select the Expression button.
Select the OR button.
Create the Expression TYPE == shear.
Select the Expression button.
Select OK.
For the example.dip file, this query should create a new file with 9 rows.
Note that all entries in the TYPE column are either "fault" OR "shear".
***************IMPORTANT NOTE!!!!!*********************
This illustrates the following important point about querying for multiple entries in a single column – you MUST use the OR operator between Expressions, and NOT the AND operator. It is a common mistake to attempt to use the AND operator for this purpose. However, a logical AND in this type of query will not find any matches in the file, since a given cell in the grid cannot be equal to (==) two different strings at the same time. So always remember to use the OR operator when querying for multiple entries in a single column.
*****************************************************
This form of query can be extended to any number of Expressions, for example:
TYPE == fault || TYPE == shear || TYPE == qtzvein || TYPE == bedding
will find all fault, shear, qtzvein and bedding entries in the TYPE column. If you only wish to EXCLUDE a single entry, it can be more easily done with the NOT EQUALS (!=) operator, for example:
TYPE != joint
will produce the same results as the above four expression query, for the example.dip file.
