Types ¶
type Provider ¶
type Provider struct {
// contains filtered or unexported fields
}
Provider implements the Provider interface for SQL Server
func (*Provider) ConvertFieldType ¶
ConvertFieldType converts YAML field type to SQL Server-specific SQL type
func (*Provider) GenerateAddColumn ¶
GenerateAddColumn generates ALTER TABLE ADD statement
func (*Provider) GenerateAlterColumn ¶
func (*Provider) GenerateCreateIndex ¶
GenerateCreateIndex generates CREATE INDEX statement for SQL Server
func (*Provider) GenerateCreateTable ¶
func (*Provider) GenerateDropColumn ¶
GenerateDropColumn generates ALTER TABLE DROP COLUMN statement
func (*Provider) GenerateDropForeignKeyConstraint ¶
func (*Provider) GenerateDropIndex ¶
GenerateDropIndex generates DROP INDEX statement for SQL Server
func (*Provider) GenerateDropTable ¶
GenerateDropTable generates DROP TABLE statement
func (*Provider) GenerateDropTableCascade ¶ added in v1.0.0
GenerateDropTableCascade generates a DROP TABLE statement for SQL Server. SQL Server does not support CASCADE on DROP TABLE, so this is an alias for GenerateDropTable.
func (*Provider) GenerateForeignKeyConstraint ¶
func (*Provider) GenerateForeignKeyConstraints ¶
func (*Provider) GenerateJunctionTable ¶
func (*Provider) GenerateRenameColumn ¶
GenerateRenameColumn generates sp_rename statement for column
func (*Provider) GenerateRenameTable ¶
GenerateRenameTable generates sp_rename statement for table
func (*Provider) GenerateUpsert ¶ added in v1.0.0
func (p *Provider) GenerateUpsert(table string, conflictKeys []string, columns []string, valueLiterals [][]string) string
GenerateUpsert generates a MERGE INTO statement for SQL Server. If all columns are conflict keys, the WHEN MATCHED clause is omitted. The valueLiterals are pre-formatted SQL literals and are not re-quoted.
func (*Provider) GetDatabaseSchema ¶
GetDatabaseSchema extracts schema information from a SQL Server database
func (*Provider) GetDefaultValue ¶
GetDefaultValue converts default value references to SQL Server-specific values
func (*Provider) HistoryTableDDL ¶ added in v1.0.0
HistoryTableDDL returns the CREATE TABLE IF NOT EXISTS statement for the makemigrations_history migration-tracking table, using this provider's SQL dialect.
func (*Provider) InferForeignKeyType ¶
func (*Provider) IsAlreadyExistsError ¶ added in v1.0.0
IsAlreadyExistsError returns true when err indicates an object already exists in the database.
func (*Provider) IsNotFoundError ¶ added in v1.0.0
IsNotFoundError returns true when err is a SQL Server "does not exist" error (error codes 3701 / 4902).
func (*Provider) Placeholder ¶ added in v1.0.0
Placeholder returns the bind-parameter placeholder for the nth argument (1-indexed).
func (*Provider) SetTypeMappings ¶ added in v1.0.0
SetTypeMappings sets user-defined type mappings for this provider.
func (*Provider) SupportsOperation ¶
SupportsOperation checks if SQL Server supports a specific operation
