OBE-14759:SET INTERVAL is not legal on this table

• OceanBase error code: 4731

• SQLSTATE: HY000

• Error cause: The SET INTERVAL clause is specified. The ALTER TABLE SET INTERVAL statement applies only to RANGE partitioned tables with a single partitioning key column. Furthermore, this partitioned table cannot have a MAXVALUE partition.

• Solution: Use SET INTERVAL only on valid tables.

OBE-14760:ADD PARTITION is not permitted on Interval partitioned objects

• OceanBase error code: 6269

• SQLSTATE: HY000

• Error cause: Adding a partition to an interval-partitioned object using the ALTER TABLE ADD PARTITION statement.

• Solution: Do not perform this operation on interval-partitioned objects. Insert a row to create a new partition.

OBE-14761:MAXVALUE partition cannot be specified for Interval partitioned objects

• OceanBase error code: 6270

• SQLSTATE: HY000

• Error cause: A partition or subpartition with a MAXVALUE upper limit is created on an interval partition/subpartition object.

• Solution: Do not create a partition or subpartition with a MAXVALUE upper limit.

OBE-14767: Cannot specify this interval with existing high bounds

• OceanBase error code: 6271

• SQLSTATE: HY000

• Error cause: The specified interval conflicts with the existing upper bound of the last partition. This combination may render future upper bound dates invalid.

• Solution: If performing a CREATE TABLE operation, try specifying a different upper bound value or a different interval for the last partition. If performing an ALTER TABLE SET INTERVAL operation, choose a different interval, or modify the table to change the upper bound of the last partition.

OBE-16000: standby tenant is read only

• OceanBase error code: 4688

• SQLSTATE: HY000

• Error cause: The standby cluster supports only read operations. Write statements such as DDL will trigger this error.

• Solution: To modify the standby cluster, you need to perform a role switch to become the primary cluster.

## OBE-19010: Cannot insert XML fragments

• OceanBase error code: 7411
• SQLSTATE: 42000
• Error cause: Attempt to insert an invalid XML document.
• Solution:
  1. Check the XML data: You can check whether the XML data to be inserted is complete and ensure that the data complies with XML document specifications.
  2. Use the XMLType data type: You can use the XMLType data type to store XML data in a separate XMLType column.

OBE-19012: Cannot convert XML fragment to the required datatype

• OceanBase error code: 7406
• SQLSTATE: 42000
• Error cause: Data type mismatch or invalidity when converting an XML fragment to the required data type.
• Solution: Check whether the data type or XML data is correct.

OBE-19025: EXTRACTVALUE cannot extract values of multiple nodes

• OceanBase error code: 7405
• SQLSTATE: 42000
• Cause: The EXTRACTVALUE function cannot extract values from multiple nodes.
• Solution: Use other functions or redesign the query statement.

OBE-19026: EXTRACTVALUE can only retrieve value of leaf nodetoo small

• OceanBase error code: 7410
• SQLSTATE: 42000
• Cause: When using the EXTRACTVALUE function, you attempt to extract a value from a non-leaf node.
• Solution: Check whether the XPath expression is correct and ensure it points to a leaf node.

OBE-19044: character length specified for XMLSerialize is too small

• OceanBase error code: 7408
• SQLSTATE: 42000
• Cause: The specified character length is too small when using the XMLSerialize function.
• Solution: Check the character length or data size to ensure it is sufficient to accommodate all data.

OBE-19102: XQuery string literal expected

• OceanBase error code: 7423

• SQLSTATE: 42000

• Cause: A string literal containing an XQuery expression is missing.

• Solution: Specify the XQuery expression as a string literal.

OBE-19110:unsupported XQuery expression

• OceanBase error code: 7428

• SQLSTATE: 42000

• Cause: The specified expression in the XQuery is not supported.

• Solution: Rewrite the XQuery using a supported expression.

OBE-19114:XPST0003 - error during parsing the XQuery expression : %.*s

• OceanBase error code: 7422

• SQLSTATE: 42000

• Cause: An error occurred while parsing the XQuery expression.

• Solution: Check the detailed error message for possible causes.

OBE-19118:XQST0066 - duplicate default namespace definition - %s

• OceanBase error code: 7420

• SQLSTATE: 42000

• Cause: Multiple default namespace declarations use the given namespace URI.

• Solution: Remove duplicate default namespace definitions.

OBE-19208:parameter %d of function XMLELEMENT must be aliased

• OceanBase error code: 7413
• SQLSTATE: 42000
• Cause: The nth attribute parameter of the XMLELEMENT() function has no alias.
• Solution:
  1. Check the syntax of the attributes in the XMLELEMENT() function to ensure it is correct and valid.
  2. Ensure that an alias is specified for the attribute parameter in the XMLELEMENT() function.

OBE-19224:XPTY0004 - XQuery static type mismatch: expected - node()* got -

• OceanBase error code: 7425

• SQLSTATE: 42000

• Cause: The expression cannot be used because its static type does not match the context in which it is used.

• Solution: Fix the expression to have the desired type or add appropriate conversion functions to the expression.

OBE-19253:XPST0033 - too many declarations for namespace prefix %.*s

• OceanBase error code: 7424

• SQLSTATE: 42000

• Cause: The query preamble contains multiple declarations for the same namespace prefix.

• Solution: Remove duplicate definitions of the namespace prefix.

OBE-19279:XPTY0004 - XQuery dynamic type mismatch: expected singleton sequence - got multi-item sequence

• OceanBase error code: 7421

• SQLSTATE: 42000

• Error cause: The input XQuery sequence contains more than one item.

• Solution: Modify the XQuery expression to return a sequence of a single item.

OBE-19276:XPST0005 - XPath step specifies an invalid element/attribute name: %.*s

• OceanBase error code: 7426

• SQLSTATE:42000

• Error cause: The XPATH step specifies an invalid element or attribute name that does not match any node based on the input XML schema or structure.

• Solution: Modify the element or attribute name.

OBE-19277:XPST0005 - XPath step specifies an item type matching no node: %.*s

• OceanBase error code: 7427

• SQLSTATE:42000

• Error cause: The item type specified in the XPath step does not match any node based on the input XML schema or structure.

• Solution: Modify it to a type node that matches.
