Display SQL Results from an External Database Macro

If you want to display SQL results from an external database in a table, you can easily accomplish this with a custom script macro.

External database example

For this example, we are going to use data from an external pet store database. To display a table with this store data, follow these steps: 

1. Create a resource to configure an external database connection. 

   See External Database Connection for more information.

2. Select the Create Macro button on the Macro page. 

3. Select Custom Script Macro.
4. Configure your custom script macro by filling out the following fields: 
   1. Key: pet-store-table
   2. Name: Pet store database table
   3. Description: Table displaying SQL results from an external pet store database
   4. Body Type: None
   5. Output Type: Block
   6. Skip the Parameter section.

   7. Enter the following code for Macro Code: 
      

      import com.onresolve.scriptrunner.db.DatabaseUtil
      import groovy.xml.MarkupBuilder
      
      /* You will replace 'petstore' with whatever you named your pool when
      configuring your Resource. */
      def rows = DatabaseUtil.withSql('petstore') { sql ->
          sql.rows('select NAME, SPECIES, ID From petstore')
      }
      
      def writer = new StringWriter()
      /* Notice our use of Groovy’s MarkupBuilder here. This is a helper class for creating XML or HTML markup.
      It’s very important to use the MarkupBuilder here to ensure your HTML is safe. */
      def builder = new MarkupBuilder(writer)
      
      builder.table('class': 'aui') {
          tr {
              rows.first().keySet().each { key ->
                  th {
                      mkp.yield(key)
                  }
              }
          }
          rows.each { columns ->
              tr {
                  columns.each { cell ->
                      td {
                          mkp.yield(cell.value)
                      }
                  }
              }
          }
      }
      
      return writer.toString()
