Peek at table shape and metadata

Displays table dimensions, column names, and data types without loading data. Useful for very large tables where you only want metadata.

Usage

peek_columns(con, table, schema = "llds")

Arguments

con

A DBI connection object.

table

Character. Table name or quoted schema.table format.

schema

Character. Schema name. Default: "llds". Ignored if table includes schema prefix.

Value

Invisibly returns a data.frame with column metadata (name and type). Called for display side effect.

Examples

if (FALSE) { # \dontrun{
con <- create_connection()
peek_columns(con, table = "LLDS_HDR_20240315HAC")
safe_disconnect(con)
} # }
