# readers.sqlite

The SQLite point cloud reader allows you to read data stored in a SQLite database using a scheme that PDAL wrote using the writers.sqlite writer. Much like the writers.oci and writers.pgpointcloud, the SQLite driver stores data in tables that contain rows of patches. Each patch contains a number of spatially contiguous points

Dynamic Plugin

This stage requires a dynamic plugin to operate

## Example

    {
      "pipeline":[
        {
          "type":"readers.sqlite",
          "connection":"inputfile.sqlite",
          "query":"SELECT b.schema, l.cloud, l.block_id, l.num_points, l.bbox, l.extent, l.points, b.cloud\r\n                      FROM simple_blocks l, simple_cloud b\r\n                     WHERE l.cloud = b.cloud and l.cloud in (1)\r\n                    order by l.cloud"
        },
        {
          "type":"writers.las",
          "filename":"outputfile.las"
        }
      ]
    }

query
  SQL statement that selects a schema XML, cloud id, bbox, and extent [Required]
