 - Make sure that you're referencing the root Delta Lake folder in the [OPENROWSET](./develop-openrowset.md) function or external table location.
   - The root folder must have a subfolder named `_delta_log`. The query fails if there's no `_delta_log` folder. If you don't see that folder, you're referencing plain Parquet files that must be [converted to Delta Lake](../spark/apache-spark-delta-lake-overview.md?pivots=programming-language-python#convert-parquet-to-delta) by using Apache Spark pools.
   - Don't specify wildcards to describe the partition schema. The Delta Lake query automatically identifies the Delta Lake partitions.
-- Delta Lake tables that created in the Apache Spark pools are automatically available in serverless SQL pool, but the schema is not updated (public preview limitation). If you add the columns in the Delta table using Spark pool, the changes will not be shown in serverless SQL pool database.
+- Delta Lake tables that are created in the Apache Spark pools are automatically available in serverless SQL pool, but the schema is not updated (public preview limitation). If you add columns in the Delta table using a Spark pool, the changes will not be shown in serverless SQL pool database.
 - External tables don't support partitioning. Use [partitioned views](create-use-views.md#delta-lake-partitioned-views) on the Delta Lake folder to use the partition elimination. See known issues and workarounds later in the article.
 - Serverless SQL pools don't support time travel queries. Use Apache Spark pools in Synapse Analytics to [read historical data](../spark/apache-spark-delta-lake-overview.md?pivots=programming-language-python#read-older-versions-of-data-using-time-travel).
 - Serverless SQL pools don't support updating Delta Lake files. You can use serverless SQL pool to query the latest version of Delta Lake.
