Feat explicit UUID mysql
add: Fn to remove constraint from a table
…limit add: Fn to determine dialect-specific byte insertion limit
* If records go beyond 1000000, the ID returned by the oracle driver is of type float64 instead of uint(uint64) * To mitigate this issue, introducing the `primary` struct * The `primary` struct implements the `Scanner` interface to convert float64 and int64 into a unit ID * The `primary` struct implements the `Valuer` interface to return the uint value of the ID it encapsulates * Introducing the `ORM` struct which makes use of the `primary` struct to encapsulate the ID returned by the DB
* This is to mitigate the scenario where the reference to the rowid of the oracle entry is returned as an int64. * This int64 is converted to uint internally by the Scan() implementation of the `primary` struct * Hence, we need to access that converted value by checking if the primary field is of type `primary`
Fix float64 oracle overflow
refactor: Export `Primary` struct outside gorm package
refactor: Remove primary key and foreign key custom structs
refactor: Use primaryField.Field.Uint to get uint when resolving row ID
feat: add support for setting nullable

When the no. of rows > 1,000,000, then the query
SELECT id FROM table_name WHERE rowid = rowIDresults in theidvariable having the value1.021e+6which cannot be converted touintusingstrconv.ParseUint.Instead, if
idis declared with typefloat64. Then no such issues are observed since*sql.DBwill resolve the ID as float64 internally.
