public Query bindValue(String var,
                       Object val)
```
    Description copied from interface: Query
    
    Bind named parameter var with value val in query statement.
    
    Specified by:
    
    bindValue in interface Query
    
    Parameters:
    
    var - variable in query statement (:var).
    
    val - value of the variable.
    
    Returns:
    
    this query
  - bindValue
```
public Query bindValue(int index,
                       Object val)
```
    Description copied from interface: Query
    
    Bind a positional parameter present in the statement (?index in XWQL) with a value. It is recommended to use named parameters if it acceptable, see Query.bindValue(String, Object).
    
    Specified by:
    
    bindValue in interface Query
    
    Parameters:
    
    index - index of positional parameter. Index starting number depends on the query language. According to the JPQL standard index should start from 1.
    
    val - value of the variable.
    
    Returns:
    
    this query
  - bindValues
```
public Query bindValues(List<Object> values)
```
    Description copied from interface: Query
    
    Bind a list of positional parameters values. This method is a convenience method allowing passing a list of values in one call instead of multiple calls to Query.bindValue(int, Object).
    
    Specified by:
    
    bindValues in interface Query
    
    Parameters:
    
    values - list of positional parameters values.
    
    Returns:
    
    this query
    
    See Also:

public QueryParameter bindValue(String var)
```
    Description copied from interface: Query
    
    Bind named parameter var with a value that will be constructed using calls to QueryParameter.literal(String), QueryParameter.anychar() and QueryParameter.anyChars(). In order to perserve the fluent API, it's also possible to call QueryParameter.query() to get back the Query.
    
    Specified by:
    
    bindValue in interface Query
