    【Question】
    How many orders were shipped in 1994? orders shipped in 1994 refer to l_orderkey where year(l_shipdate) = 1994;

    【Evidence】
    orders shipped in 1994 refer to l_orderkey where year(l_shipdate) = 1994;

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT COUNT(l_orderkey) FROM lineitem WHERE STRFTIME('%Y', l_shipdate) = '1994'
