Model names must start with a letter and are typically spelled in PascalCase. Model names must adhere to the following regular expression: *. You must define at least one of the following attributes per model: Every record of a model must be uniquely identifiable. In this example, the target database is available with the following credentials: datasource db is convention - however, you can give your data source any name - for example, datasource mysql or datasource data.Įxamples Specify a PostgreSQL data source. You can only have one datasource block in a schema. Available in preview for PostgreSQL only in Prisma versions 4.5.0 and later. List of strings (PostgreSQL extension names)Īllows you to represent PostgreSQL extensions in your schema. The field is named relationMode in versions 4.5.0 and later, and was previously named referentialIntegrity. Sets whether referential integrity is enforced by foreign keys in the database or emulated in the Prisma Client. If you are using a prisma:// URL in the url argument, you may use the Data Browser as an alternative to Prisma Studio. The only exception to this is the prisma studio command. If you use a connection pooler URL in the url argument (for example, if you use the Data Proxy or pgBouncer), Prisma CLI commands that require a direct connection to the database use the URL in the directUrl argument. Allows you to use a cloud-hosted database as the shadow database.Ĭonnection URL for direct connection to the database. Most connectors use the syntax provided by the database.Ĭonnection URL to the shadow database used by Prisma Migrate. The OldID and OldAccountID columns are of type VARCHAR(40).String ( postgresql, mysql, sqlite, sqlserver, mongodb, cockroachdb)ĭescribes which data source connectors to use.Ĭonnection URL including authentication info. INNER JOIN `AccountMaster` AS B ON A.OldAccountID=B.OldIDĪny idea how do I mitigate this issue? I'm pretty sure that the 36 character OldID is creating issues after migration even though all the columns 'ID' & 'OldID' in AccountMaster as well as 'ID' & 'OldAccountID' in Transactions in MySQL are indexed. #Migrating mysql uuid to mssql uniqueidentifier update
The issue now is that when I run a query like below to update the Transactions table with the new IDs, it takes hours and never really completes. So, I manage to migrate all 45K accounts in my AccountMaster as well as 1M transactions in my Transactions table while maintaining the old ID (UNIQUEINDENTIFIER) as OldID in both AccountMaster and Transactions.īelow is the scenario after migration in my MySQL database AccountMaster In my tables, I have migrated the AccountMaster ID as OldID and I'm creating new ID which are of type INT (Auto Increment).
In the older application AccountMaster has ID as UNIQUEIDENTIFIER and Transactions table references it. The issue is with 2 tables particularly as below.ĪccountMaster which has approx 45,000 accounts and Transactions which has approx 1M rows.
In my new application that I'm developing using PHP & MySQL, I wrote the script to migrate all the data from MS-SQL to MySQL. The earlier developer used UNIQUEIDENTIFIER as the primary key for all tables that needed one.
My client's old application is developed in.
