Select action

The action will execute an SQL query that can return multiple results, it has limitations on the query and suited only for SELECT type of queries.

Select

In SQL query you can use clause variables with specific data types. Internally we use prepared statements, so all incoming data is validated against SQL injection, however we had to build a connection from JavaScript types to the SQL data types therefore when doing a prepared statements, you would need to add :type to each prepared statement variable.

For example if you have a following SQL statement:

SELECT
FROM users
WHERE userid = @id AND language = @lang

you should add :type to each @parameter so your SQL query will looks like this:

SELECT
FROM users
WHERE userid = @id:number AND language = @lang:string

Following types are supported:

  • string
  • number
  • bigint
  • boolean
  • float
  • date

Config Fields

  • Query to provide request string.

Input Metadata

Component supports dynamic incoming metadata - as soon as your query is in place it will be parsed and incoming metadata will be generated accordingly.

Execute stored procedure action

This action calls stored procedure

Config Fields

  • Stored procedure - a name of a procedure to call, can be selected from the dropdown list

Input Metadata
