The main interface tool is SQL Server Management Studio (SSMS), which consists of a client and a server. SQL Server supports the standard SQL language (ANSI SQL) as well as its own proprietary language (T-SQL or Transact SQL). SQL Server to Databricks (Easy Migration Method) Recent versions have built-in Spark support, which allows users to analyze massive volumes of data using Spark SQL with minimal additional setup. It also has a powerful querying layer for business analysis and integrates well with reporting solutions like Power BI. Microsoft SQL Server is a relational database management system that can handle large amounts of data, with support for hundreds of simultaneous running cores and petabyte-scale storage. The selection between the two databases should be made based on the particular application scenario you are considering. Think of migrating your data from SQL Server to Postgres? On the face of it, moving to PostgreSQL can be advantageous due to its open-source nature and advanced data types, but MSSQL possesses unique capabilities as well.

Learn about SQL Server vs Postgres points of comparison, and the numerous advantages of Postgres. Target Schema cannot hold both records, because the target schema marked the equivalent column as UNIQUE in MySQL.ĭon't make the target column UNIQUE just because that word happened to appear in the MSSQL DB It means something different there.This blog will give you the lowdown on migrating from SQL Server to PostgreSQL. Use MySQL Workbench Migration Wizard to migrate this database to MySQL.Ĥ. This is valid since UNIQUEIDENTIFIER is just a UUID field.ģ. Insert two records with the same UUID into that column.
Create a MSSQL column of type UNIQUEIDENTIFIER.Ģ. All subsequent records belonging to that User ID fail, because the Target column is UNIQUE.ġ.
Making the Target column UNIQUE means that only one record belonging to each User ID can be inserted. In my case the column is being used for a "User ID". When this creates Target MySQL schema of type "VARCHAR(64) UNIQUE" suddenly MySQL cannot hold all the source data any longer. There is nothing unique about data in the source table - It's just a name for describing a UUID column. MSSSQL UNIQUEIDENTIFIER is a data type for holding UUIDs (or "GUIDs" in MS-speak). Since MSSQL and MySQL schema do not have complete 1:1 mappings, it seems someone decided that the MSSQL cdata type called "UNIQUEIDENTIFIER" should become in MySQL a column of type "VARCHAR(64) UNIQUE". I am unable to complete a MSSQL to MySQL Migration and I believe this si caused by a misinterpretation of Source Schema on the part of MySQL Workbench.
