public class ImpalaUtils
extends Object
```
Builds Impala-safe quoted identifiers for dynamic SQL. JDBC ? placeholders apply to values, not table references, so identifiers must be quoted and escaped explicitly.

All Methods Static Methods Concrete Methods
Modifier and Type	Method	Description
`static String`	`qualifiedTableForMetadataSql(TableName tableName)`	`schema.table` for metadata statements, upper-casing each segment then quoting so names cannot break out of identifier context.
`static String`	`quoteIdentifier(String identifier)`	Wraps a single identifier in backticks; doubles any embedded backticks.
