SQL Editor
Acho Team understands that sometimes the desired data transformation action to be performed is just too complex or inefficient to be done via a sequence of available actions. This is why Acho offers a SQL editor to allow our advanced users proficient in SQL to have the flexibility to perform more advanced actions. The SQL Editor on Acho supports standard SQL syntax and functions.
- 1.The SQL Editor does not support line-level execution. That is, everything in the editor will be executed all at once. Therefore, please make sure to include a semicolon
;at the end of the query and not to have empty lines after the semicolon;. Also, the SQL Editor cannot include more than two queries at a time, that is, more than two semicolons;. - 2.All table names must have a prefix of
SQL_EDITOR_and a suffix of_TABLE. - 3.When using the
JOINorUNIONstatements, you have to import all needed tables into the project first. The SQL Editor can only access tables within the current project. - 4.when using the
JOINstatement, if there are two columns with the same name, the query will run into an error. join a table to itself. For example, if you join a table to itself (that isSELF JOIN) and select all columns, then an error occurs due to duplicate column names.
SELECT *
FROM SQL_EDITOR_us_states_TABLE AS A
LEFT JOIN us_states AS B
ON A.state_name = B.state_name
You have can change your query like the following.
SELECT A.state_name AS state_name, B.state_name AS state
FROM SQL_EDITOR_us_states_TABLE AS A
LEFT JOIN us_states AS B
ON A.state_name = B.state_name
