Ingres9Dialect
```
public class IngresDialect
extends Dialect
```
An SQL dialect for Ingres 9.2.
Known limitations:
- Only supports simple constants or columns on the left side of an IN, making (1,2,3) in (...) or (subselect) in (...) non-supported.
- Supports only 39 digits in decimal.
- Explicitly set USE_GET_GENERATED_KEYS property to false.
- Perform string casts to varchar; removes space padding.

    从类复制的说明: Dialect
    
    Does this dialect support some form of limiting query results via a SQL clause?
    
    覆盖:
    
    supportsLimit 在类中 Dialect
    
    返回:
    
    True if this dialect supports some form of LIMIT.
  - supportsLimitOffset
```
public boolean supportsLimitOffset()
```
    从类复制的说明: Dialect
    
    Does this dialect's LIMIT support (if any) additionally support specifying an offset?

    覆盖:
    
    getLimitString 在类中 Dialect
    
    参数:
    
    querySelect - The query to which to apply the limit.
    
    offset - The offset of the limit
    
    limit - The limit of the limit ;)
    
    返回:
    
    The modified query statement with the limit applied.
  - supportsVariableLimit
```
public boolean supportsVariableLimit()
```
    从类复制的说明: Dialect
    
    Does this dialect support bind variables (i.e., prepared statement parameters) for its limit/offset?
    
    覆盖:
    
    supportsVariableLimit 在类中 Dialect
    
    返回:
    
    True if bind variables can be used; false otherwise.
  - useMaxForLimit
```
public boolean useMaxForLimit()
```
    从类复制的说明: Dialect
    
    Does the LIMIT clause take a "maximum" row number instead of a total number of returned rows?
    This is easiest understood via an example. Consider you have a table with 20 rows, but you only want to retrieve rows number 11 through 20. Generally, a limit with offset would say that the offset = 11 and the limit = 10 (we only want 10 rows at a time); this is specifying the total number of returned rows. Some dialects require that we instead specify offset = 11 and limit = 20, where 20 is the "last" row we want relative to offset (i.e. total number of rows = 20 - 11 = 9)
    So essentially, is limit relative from offset? Or is limit absolute?
    
    覆盖:
    
    useMaxForLimit 在类中 Dialect
    
    返回:
    
    True if limit is relative from offset; false otherwise.
  - getDefaultMultiTableBulkIdStrategy
```
public MultiTableBulkIdStrategy getDefaultMultiTableBulkIdStrategy()
```
    覆盖:
    
    getDefaultMultiTableBulkIdStrategy 在类中 Dialect

```
public String getCurrentTimestampSQLFunctionName()
```
    从类复制的说明: Dialect
    
    The name of the database-specific SQL function for retrieving the current timestamp.
    
    覆盖:
    
    getCurrentTimestampSQLFunctionName 在类中 Dialect
    
    返回:
    
    The function name.
  - supportsSubselectAsInPredicateLHS
```
public boolean supportsSubselectAsInPredicateLHS()
```
    从类复制的说明: Dialect
    
    Are subselects supported as the left-hand-side (LHS) of IN-predicates.
    In other words, is syntax like "... IN (1, 2, 3) ..." supported?
    
    覆盖:
    
    supportsSubselectAsInPredicateLHS 在类中 Dialect
    
    返回:
    
    True if subselects can appear as the LHS of an in-predicate; false otherwise.
  - supportsEmptyInList
```
public boolean supportsEmptyInList()
```
    从类复制的说明: Dialect
    
    Does this dialect support empty IN lists?
    For example, is [where XYZ in ()] a supported construct?
    
    覆盖:
    
    supportsEmptyInList 在类中 Dialect
    
    返回:
    
    True if empty in lists are supported; false otherwise.
  - supportsExpectedLobUsagePattern
```
public boolean supportsExpectedLobUsagePattern()
```
    从类复制的说明: Dialect
    
    Expected LOB usage pattern is such that I can perform an insert via prepared statement with a parameter binding for a LOB value without crazy casting to JDBC driver implementation-specific classes...
    Part of the trickiness here is the fact that this is largely driver dependent. For example, Oracle (which is notoriously bad with LOB support in their drivers historically) actually does a pretty good job with LOB support as of the 10.2.x versions of their drivers...
    
    覆盖:
    
    supportsExpectedLobUsagePattern 在类中 Dialect
    
    返回:
    
    True if normal LOB usage patterns can be used with this driver; false if driver-specific hookiness needs to be applied.
  - supportsTupleDistinctCounts
```
public boolean supportsTupleDistinctCounts()
```
    从类复制的说明: Dialect
    
    Does this dialect support `count(distinct a,b)`?
    
    覆盖:
    
    supportsTupleDistinctCounts 在类中 Dialect
    
    返回:
    
    True if the database supports counting distinct tuples; false otherwise.
