I've got a large file geodatabase that contains a polyline feature class of water-pipes. The feature class have many fields, but the ones that I'm interested in is that of the water-pipe's Length and Locality Name.

I'm looking for a way to use the Table Select tool to generate a summary table in the same file geodatabase which summarizes the water-pipe's shape lengths for each locality. The output should be file geodatabase table which looks like this example:

  1. Locality 1 24395.66118
  2. Locality 2 19572.35849
  3. Locality 3 17474.87241
  4. Locality 4 16205.04598
  5. etc...

I've tried to follow this link which describes the SQL syntax for such operation. I didn't get where to write it and how. This is the syntax I probably need from the link:

SELECT STATE_NAME, SUM(POP1990) as TotalPopulation
FROM counties

You can use the Summary Statistics GP tool for that. Choose Shape_length field to be the Statistics field, and Locality Name field to be the case field.

  • This is a good answer but I'm looking for a way to do it by a SQL expression. How can I write a Stand-Alone SQL expression that will edit my data and will give me a new table?

    You cannot do it with out-of-the-box tools for a file geodatabase (SELECT * FROM forms the first part of the SQL expression and is automatically supplied for you, you cannot change this). If you could load your data into a DBMS, then you would be able to execute this query. The page you refer to, is for file gdb API use (or in ArcObjects). Commented Nov 12, 2015 at 10:59

    The most important aspect of file geodatabases is that it doesn't have a database behind it. It doesn't support CREATE TABLE foo AS SELECT ... The canonical technique for creating a new summary table is to use Summary Statistics.
