SqlAlterTableDropConstraint

public SqlAlterTableDropConstraint(org.apache.calcite.sql.parser.SqlParserPos pos,
                                   org.apache.calcite.sql.SqlIdentifier tableName,
                                   org.apache.calcite.sql.SqlIdentifier constraintName,
                                   boolean ifTableExists)

Creates an alter table drop constraint node.

参数:

pos - Parser position

tableName - Table name

constraintName - Constraint name

ifTableExists - Whether IF EXISTS is specified

方法详细资料

getConstraintName

public org.apache.calcite.sql.SqlIdentifier getConstraintName()

getOperandList

public List<org.apache.calcite.sql.SqlNode> getOperandList()

指定者:

getOperandList 在类中 org.apache.calcite.sql.SqlCall

unparse

public void unparse(org.apache.calcite.sql.SqlWriter writer,
                    int leftPrec,
                    int rightPrec)

覆盖:

unparse 在类中 SqlAlterTable
