Method Detail

appendQueryPlaceholder

int appendQueryPlaceholder(StringBuilder queryBuilder,
                           int index,
                           int current)

Append a parameter placeholder in the query.

The index starts at 0.

• When index == current indicates it is a new parameter and therefore the same * value should be returned.
• When index < current indicates the builder wants to reuse a parameter. The implementation can either return the same value to indicate the parameter can be reused or return the next index to use (which is shall be the current value

Parameters:

queryBuilder - the builder to append to

index - the parameter placeholder index

Returns:

the index at which the parameter placeholder could be added
