            sqlGetDouble
      (query [, value1, ... ])
         

Variables replace the parameters in the command. The variable type must coincide with the parameter declared in the command. These variables are available in a 'select' or 'update' type declaration. We have the following types:

• $(sz) string
• $(m) memo
• $(l) long
• $(s) short
• $(b) byte
• $(d) double
• $(f) float
• $(ts) timestamp
• $(dt) date
• $(tm) time
• $(dur) timespan in milliseconds (ms)

The following substitution parameters (only valid for an "update") are automatically replaced with a value and don't need a linked variable.

• $(id) Generates an identifier
• $(id:NmsTrackingLogId) Generates an identifier using a specific sequence
• $(curdate) Current date and time

Using variables does not alter Adobe Campaign performances. The SQL query must select a single line and a single numeric type field. The operator must have the 'sql' right to use this function, otherwise an exception is raised. Example:

      var number = sqlGetDouble('select price from priceTable where sTaxes =$(d) order by tsCreated DESC LIMIT 1', taxes)
