Column Definitions
The basic attributes of a column are the name of the column, the data type, whether the column is a primary key, the relative path and the depth. The add-in uses the depth attribute to extract nodes from hierarchical data.
Mark up column attributes in the block of the schema file. You can also provide a description of each attribute using the desc property.

The following sections provide more detail on using paths to extract columns and rows. To see the column definitions in a complete schema, refer to Customizing Schemas.
Mapping SELECT Projection to GraphQL Fields
Control the building process of a GraphQL field path with the properties listed below:-
The other:possiblePaths property is used to specify the base paths that select the column's value.
Base paths start with a '/' and contain the full path to the last GraphQL nested object.
<rsb:info title="Labels" desc="Lists information about the different labels you can apply to an issue." other:possiblePaths="{'path':'/repository/labels/edges/node','Name':{'path':'/repository/label'}}" other:paginationObjects="{'labels':{'cursorPath':'after','cursorType':'String','pageSizeArgumentPath':'first','pageSizeArgumentType':'Int','depth':'1''paginationType':'Cursor','isConnection':'True','pageInfo':['endCursor','hasNextPage','hasPreviousPage','startCursor']}}">The following GraphQL query is based on the above script example:{ # base path=/repository/labels/edges/node repository { labels { edges { node { ... } } } } } -
The other:relativePath property must be specified for each column. This property is used in conjuction with the other:possiblePaths property to build the GraphQL field path.
<attr name="Name" xs:type="string" other:relativePath="name" desc="Identifies the label name." />
Based on the above script example the add-in will build the following GraphQL query:{ # base path=/repository/labels/edges/node repository { # depth=1 labels { # depth=2 edges { node { name # path=base path + relative path. } } } } } -
Use the other:depth property to specify an element inside a specific GraphQL object. The indexes are 1-based. If this attribute is not specified then the default value will be equal to the last nested GraphQL object.
<attr name="RepositoryName" xs:type="string" other:relativePath="name" desc="The name of the repository." other:depth="1" />
The following GraphQL query is built from the above script example:{ # base path=/repository/labels/edges/node repository { # depth=1 name # This is mapped to the RepositoryName column labels { # depth=2 edges { node { ... } } } } } -
Use the other:fragment property to specify a group of fields. This property can be used when the GraphQL server returns an array of objects and the add-in may need to push this info as an aggregate.
<attr name="ColumnValues" xs:type="string" other:relativePath="column_values" desc="Column values." other:fragment="fragment ItemColumnValues on ColumnValue { id \\r\\n value }" />Based on the above script example, the add-in will build the following GraphQL query:query { items { column_values { ...ItemColumnValues } } } fragment ItemColumnValues on ColumnValue { id value } -
Use the other:canbesliced property enable slicing behavior in the add-in
For example,
SELECT * FROM Table WHERE Col IN ('1','2','3')becomesSELECT * FROM Table WHERE Col=1 SELECT * FROM Table WHERE Col=2 SELECT * FROM Table WHERE Col=3
-
Use the other:mirror property to reflect the value specified in the criteria. Use on columns that are not specified in the server response.
For example:
SELECT * FROM Table WHERE Col=X (If other:mirror=true the add-in will artificially set the value of Col to X for every row.)
-
Use references to reference the key column of the parent table. Example: If there are two tables Orders and OrderLineItems and the OrderLineItems has a column OrderId, the references field for this column will be "Orders.Id".
Notes:
- Paths and column names (when used to generate the path) are case sensitive.
- At least one possible path should be specified.
- The other:relativePath property must be specified for every column. Otherwise, the add-in cannot map the SELECT column to a GraphQL field.
