public class TableName
extends QueryTreeNode

A TableName represents a qualified name, externally represented as a schema name and an object name separated by a dot. This class is misnamed: it is used to represent the names of other object types in addition to tables.

private boolean hasSchema

Constructor Detail

TableName

TableName(java.lang.String schemaName,
          java.lang.String tableName,
          ContextManager cm)

Constructor for when we have both the table and schema names.

Parameters:

schemaName - The name of the schema being referenced

tableName - The name of the table or other object being referenced

cm - The context manager

TableName

TableName(java.lang.String schemaName,
          java.lang.String tableName,
          int tokBeginOffset,
          int tokEndOffset,
          ContextManager cm)

Constructor for when we have both the table and schema names.

Parameters:

schemaName - The name of the schema being referenced

tableName - The name of the table or other object being referenced

tokBeginOffset - begin position of token for the table name identifier from parser. pass in -1 if unknown

tokEndOffset - end position of token for the table name identifier from parser. pass in -1 if unknown

cm - The context manager

Method Detail

getTableName

public java.lang.String getTableName()

Get the table name (without the schema name).

Returns:

Table name as a String

hasSchema

public boolean hasSchema()

Return true if this instance was initialized with not null schemaName.

Returns:

true if this instance was initialized with not null schemaName

getSchemaName

public java.lang.String getSchemaName()

Get the schema name.

Returns:

Schema name as a String

setSchemaName

void setSchemaName(java.lang.String schemaName)

Set the schema name.

Parameters:

schemaName - Schema name as a String

getFullTableName

java.lang.String getFullTableName()

Get the full table name (with the schema name, if explicitly specified).

Returns:

Full table name as a String

getFullSQLName

public java.lang.String getFullSQLName()

Get the full SQL name of this object, properly quoted and escaped.

toString

public java.lang.String toString()

Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.

Overrides:

toString in class QueryTreeNode

Returns:

This object as a String

equals

boolean equals(TableName otherTableName)

2 TableNames are equal if their both their schemaNames and tableNames are equal, or if this node's full table name is null (which happens when a SELECT * is expanded). Also, only check table names if the schema name(s) are null.

Parameters:

otherTableName - The other TableName.

Returns:

boolean Whether or not the 2 TableNames are equal.

equals

boolean equals(java.lang.String otherSchemaName,
               java.lang.String otherTableName)

2 TableNames are equal if their both their schemaNames and tableNames are equal, or if this node's full table name is null (which happens when a SELECT * is expanded). Also, only check table names if the schema name(s) are null.

Parameters:

otherSchemaName - The other TableName.

otherTableName - The other TableName.

Returns:

boolean Whether or not the 2 TableNames are equal.

cloneMe

public TableName cloneMe()

Clone this TableName

bind

void bind()
   throws StandardException

Bind this TableName. This means filling in the schema name if it wasn't specified.

Throws:

StandardException - Thrown on error

hashCode

public int hashCode()

Returns a hash code for this tableName. This allows us to use TableNames as keys in hash lists.

Overrides:

hashCode in class java.lang.Object

Returns:

hash code for this table name

equals

public boolean equals(java.lang.Object other)

Compares two TableNames. Needed for hashing logic to work.

Overrides:

equals in class java.lang.Object

Parameters:

other - other tableName
