fetchFieldStrict

inline fun <T> fetchFieldStrict(params: Map<String, Any?>): T

Executes the query and returns the first column of its single row, requiring exactly one row.

Strict governs how many rows came back, not whether the value is NULL: a NULL under a nullable T is still returned as null here.

The value.

REQUIRED_ATTRIBUTE_MISSING if the value is NULL and T is not nullable.
