TypeORM Legacy Naming Strategies

NamingStrategyV03

In TypeORM v1, the SHA1 hashing algorithm used in the naming strategy is applied directly to the input. In the previous versions (v0.3), the input was first encoded using encodeURIComponent.

Use this naming strategy to avoid changes in the database if your table or column names contain characters other than:

A–Z a–z 0–9 - _ . ! ~ * ' ( )

Example:

const dataSource = new DataSource({
    ...
    namingStrategy: new NamingStrategyV03(),
    ...
})

LegacyOracleNamingStrategy

Prior to Oracle 12.2, identifiers were not allowed to exceed 30 characters. Use this naming strategy to keep column names up to 30 characters.

Arguments

• shortenStrategy: can be either hash (default) or truncate.

Example:

const dataSource = new DataSource({
    ...
    namingStrategy: new LegacyOracleNamingStrategy("hash"),
    ...
})
